Any potatoes cooked in duck fat are far superior to those cooked in oil However, duck fat is pricey, I would guess 3 times more than oil. I make a shoestring potato cake called pommes darphin that is best done in duck fat. Therefore, I only make it when I am roasting a duck! If you're looking to enhance the flavor of your fries, you may want to try a combination of lard and oil that has been infused with garlic cloves, fresh thyme branches and bay leaves. In the north of France and south of Belgium this is what they use to make their frites and they are truly delicious.

Lisa, I have had the frites in France and Belgium and they were outstanding. I bought some in the French Canadian province and they claimed they were the same but the taste was not nearly the same.

Paul, I'm glad you agree with me because they really are the best! When I lived in Hon-Hergies, France (on the Belgian border) my neighbor Christienne made frites every day for lunch and dinner. It was just her, her husband and her son and she went through 220 pounds of potatoes a month!!

Half duck fat and half frying oil works out the best. The frying oil gives the consistent frying medium (also more predictible and higher smoke point) and the remaining duck fat helps to impart the flavor...even a little infused duck fat with garlic, parm, salt, pepper and parsley/chives to toss the fries in after they're cooked would be the icing on the cake!

Hog lard is great and the fries are much better than fries cooked in veg. oil. Actually, I used bacon/jowl dripping (smoked), I have plenty ... Asking for 'duck fat' is a bit of a problem ... no one around here has heard of it ... it must be one of those 'new york' things

Do a test run using peanut oil as your frying oil...and using "the icing" of infused duck fat (as fishscale28 mentioned) for a finish...much like truffle oil fries.

You get the taste benefit (hardly the cost) of the duck fat...peanut oil does the heavy lifting.

If you like it...careful with the wording on the menu as far as being all-in about "duck fat fries" You can frame it the same way truffle fries are written on a menu. Tossed - finished or drizzled with...insert the description of the infused duck fat.

No Restaurant Depot around here, I have found some duck fat online at a decent price. There is a restaurant in Oklahoma City called Mutt's Amazing Dogs that sells duck fat french fries. I love that place. We usually try and eat at a different non-chain rest. every time we make it to the city. But we have been there 3 times in a row now. Great gourmet hotdogs and hamburgers, if you are in the area try it out you'll love it. Anyway got sidetracked. They fry there french fries in duck fat all the way, which I do not think will be feasible for me. But I did see a episode of Diners Drive in and Dives where they fried the french fries and then ladled some duck fat in at the end. I still have yet to try it. I have plenty of time tho truck is still in the beginning stages. I am going to have it built. We have a brick and mortar rest. I work full time as a Deputy Sheriff and serve as a Deacon. Also serve as a liaison for different child protection teams and domestic violence. I stay busy. As you can tell from the rambling my pre-workout has kicked in, time to hit the gym!
